That's the way I understand it.
I was just looking at the truth table for the IC, but didn't want to confuse us..

What you want to shoot for in your voltage divider design,
is never allow the input on pin 2, to go so high that it cooks the chip..
Even when PV volts are at max..
I think that's what caused my chip to melt into it's socket.. LOL!
Otherwise I would have just plugged in another chip..
The voltage of my 800w array can get quite high..
